Mandibular condylar osteochondroma (OC) results in asymmetric prognathism with facial morphology and functional disturbances. The aim of this study was to explore the feasibility of computer-assisted surgical planning combined with intraoperative navigation in the treatment of condylar OC. Five patients with mandibular condylar OC were enrolled in this(More)
Gap arthroplasty, used in the treatment of temporomandibular joint (TMJ) ankylosis, is challenging, requiring resecting of massive abnormal bone formation at the skull base with complex and distorted anatomy. This study evaluated the application of image-guided navigation to gap arthroplasty. Four gap arthroplasties were performed on patients with(More)
The surgery-first approach (SFA), without presurgical orthodontic treatment, has become favoured in the treatment of dentomaxillofacial deformities. This approach has been applied in our institution since 2012. The purpose of this study was to report our experience with the SFA for skeletal malocclusion. Fifty patients with skeletal malocclusions were(More)
OBJECTIVE The association between codon 72 polymorphism of the tumour protein p53 (TP53) gene - which results in a missense mutation of arginine (R) to proline (P) - and susceptibility to hepatocellular carcinoma (HCC) is controversial. A metaanalysis was performed in order to define this relationship more precisely. METHODS Published studies of TP53(More)
PURPOSE To investigate the role of wall shear stress in aspects of the formation of fibrin sheath and intimal thickening in a dog model. METHODS Tunneled silicone 14.5-F catheters were inserted into the left internal jugular vein in eight dogs. The dogs were separated into two groups according to catheter indwelling time of 14 and 28 days. All dogs(More)
Objective: To analyze long-term mortality and patients characteristics of cardiac resynchronization therapy (CRT) for patients with chronic heart failure. Methods: In-patients with chronic heart failure who received CRT in the three medical centers(Bethune International Peace Hospital, General Hospital of Shenyang Military Command of Chinese People's(More)
Objective: To establish a digital workflow in the treatment of mandibular condylar osteochondroma with secondary dentofacial deformities using navigation and endoscope combined with orthognathic surgery. Methods: Thirty-six patients with unilateral condylar osteochondroma were analyzed retrospectively. Preoperative planning and simulation were carried out(More)
Mandibular condylar osteochondroma (OC) can result in morphological and functional disturbances, including facial asymmetry and temporomandibular joint (TMJ) dysfunction. The aim of this study was to explore the feasibility of endoscope-assisted tumour resection and conservative condylectomy via an intraoral approach. Seven patients with condylar OC were(More)
BACKGROUND Tissue-engineered bone is the most perspective and ideal prosthesis for bone defects. But the immunological reaction in allograft is unavoidable. To date there has not been an analysis of the effect of cryopreservation on osteoblast immunogenicity. In this study, we investigated the effects of fluid nitrogen cryopreservation on immunogenicity of(More)
Objective: To investigate the clinical efficacy of enhanced recovery after surgery(ERAS) in atrial caval shunting (ACS) for type Ⅱ Budd-Chiari syndrome(BCS). Methods: The clinical data of patients underwent ACS for type Ⅱ BCS in the Henan Province People's Hospital from January 2014 to June 2016 were prospectively analyzed.Randomized and single-blind,(More)
